Answer this question truthfully
### Question: What causes Hand-foot-and-mouth disease?
### Response: Hand-foot-and-mouth disease (HFMD) is most commonly caused by coxsackievirus A16, a member of the enterovirus family.
The disease is not spread from pets, but it can be spread by person to person. You may catch it if you come into direct contact with nose and throat discharges, saliva, fluid from blisters, or the stools of an infected person. You are most contagious the first week you have the disease.
The time between infection and the development of symptoms is about 3 - 7 days.
